GSC P-D Mitsubishi 4B11T High Pressure Single Conical Valve Spring and Ti Retainer Kit

The single conical design of these GSC Power Division valve springs for the Mitsubishi 4B11T engine is a key feature, allowing for a more compact and lighter retainer assembly. This isn't just about saving a few grams; it directly impacts valve control at higher RPMs by reducing the overall mass the valvetrain has to manage. When you're pushing your 4B11T hard, especially in modified applications, maintaining precise valve timing and preventing valve float becomes critical for engine health and performance. This kit is built to handle those demands.

Crafted with high-pressure single conical springs, this kit is designed to provide the necessary seat and open pressures to keep your valves securely closed, even under aggressive camshaft profiles and high engine speeds. The included titanium retainers are a significant upgrade over stock. Titanium is notably lighter than steel, which further reduces valvetrain mass, contributing to improved high-RPM response and durability. This combination of advanced spring design and lightweight titanium retainers means you're getting a well-built kit engineered to support significant performance increases in your 4B11T engine.

This kit includes everything you need to upgrade your valve springs and retainers. It's a comprehensive package for anyone serious about building a high-performance 4B11T engine. Ensure you consult the manufacturer's installation instructions for proper fitment and assembly procedures, as valve spring installation requires specific tools and knowledge to ensure correct setup and prevent damage.
